MILK-COOLER.

SPECIFICATION forming part of Letters Patent No. 268,620, dated December5, 1882. Application filed March 29, 1882. (No model.)

To all whom it may concern Be it known that 1, DAVID N. UALKINS, of

Rochelle, in the county of Ogle and State of .the catch-basin of thecover. Fig. 3 is adetail vertical sectional view of the main cover andsupplemental cover in a plane passing through the water-tube andventilating-tube, Fig. at

-is a sectional view of the water-chamber, representing the milk-can inside elevation, the

covers of the water-chamber being removed. Fig. 5 is a detail view inside elevation of the cream discharge and indicator. Fig. 6 is a detailview in horizontal transverseseotion of the cream discharge device. Fig.7 isadetail sectional view of the connection of the milkdischarge spoutwith the milk-can. Fig. 8 is aperspectiveview of the rack which retainsthe cans in place.

Preferably I make the water-chamber A of wood and line its interior withtin or galvan- Zized iron. Within the chamber are placed milk-cansB,ofheightadapted to extend above the overflow-opening a? of the chamber,said cans resting within the rack B, which latter is secured and held tothe bottom of the cham- .ber A by the hooks b.

This rack B is composed of the end pieces, b and side pieces, b securedtogether, as shown, and the latter provided with depending legs orstandards 12,

adapted to rest on the bottom of the waterchamber A and afford bearingfor the rack. This rack is adapted to fit snugly within the chamberA,andthe side and end pieces of the same are separated sufficiently from there- ,spective sides andends of the chamber A to prevent the cans B,which are secured between the said side and end pieces of the rack Bfrom approachingtoo near the sides and ends of the chamber A, whichwould interfere with wide enough to admit the cans being introducedtherein and long enough for two or three cans abreast, as the case maybe. Each can is provided at its lower end with one ortwo projectingtongues, b ,which latter are adapted to rest under the cross-pieces band hold the can in position. When it is desired to place the cans inposition in the cabinet they are turned so as to bring both projectingtongues inside or between two'cross-bars b and lowered to the bottom ofthe chamber. After they rest on the bottom of the chamber A they areturned so as to bring the tongues under the cross-bars biwhich hold themdown firmly in position, whether they are filled or not. The rack 1 3 issecured to the bottom of the chamber A by the books I) and the eyes N.If desired, the cans can be secured in position slightly above thebottom of the chamber A, and thereby enable a free circulation of waterunder as well as around the cans.

A rubber gasket, f, fits in the sleeve 01, and

through the gasket the milk-discharge tube 9 passes. Disksh, secured tothe opposite ends of the tube, fit against the inner and outer ends ofthe gasket and connect the several parts together. This tubehas freerotary movement in the gasket, and its outer end is pro? vided with aspout, l. r

The main cover 0' is provided with a rim, m, which may be formed hollowor not, as preferred,'and depends into the interior of theWater-chamber. water, forms a water-seal, and an air-chamber, a, is thusformed about the upper portion of the cans. The sides of the main coverare provided with an upwardly-extendin grim, 1", which forms a water-panon the top of said cover. A tube, 8, extends from the surface of thiscover down within the water-chamber to a point below the water-line. Thewater resulting from This rim, dipping into thethe melting of the icepasses through this tube and into the water-chamber.

O is a rubber cork or stopper, having a metallic or wooden handlesecured thereto, which latter, when the cork is in position in the tube8, extends up through the opening a in the supplemental cover E and iswithin easy reach of an attendant.

By means of this improvement the water can be retained in thewater-chamber'w and allowed to flow downward into the chamber A atsuitable intervals without necessitating the removal of the supplementalcover E to accomplish the same end. The coveris further'p'rovidetl atone end with a ventilating-tube, t, whose lower extremity communicateswith airchamber n at a point slightly below the top of the milk-cans, asindicated by the dotted lines in Fig.3, so as to be automatically closedwhen the water rises sufficiently to submerge the lower end thereof. Bythis means the water is prevented from rising above thi'spoint (thecover being air-tight) and flowing'over into the milk-cans. The upperextremity of the tubet extends above the water-rim of the supplementalcover. The rear side of the main cover 1 is provided with a catch-basin,D, which extends across the cover and is adapted to catch the waterwhich may be on the cover as the latter is swung back on its hinges.

The supplemental cover E is formed with a depending flange, to, aboutits sides. This flange rests upon the main cover and forms awater-space, 00, between the two'covers. The ventilating-tube passesthrough a hole, y, formed in the supplemental cover.

The double-walled upright cylinder F is formed at the central portion ofthe supplemental cover and extends through the same, and is providedwith a bottom, which rests slightly above the top of the main cover, Thetop of the cylinder is provided with ahollow removable cover or lid, G.The ice is placed .in this cylinder and'rests on the bottom thereof,which keeps the water in the Water-space 00 cold, and thereby maintainsthe milk at a cool temperature. The water from the ice is allowed toescape from the cylinder F through the perforations' 6 into thewater-space w.

D is an overflow-tube, rigidly secured'to the main cover near one end ofthe cooler. The upper end of this tube extends up slightly above the topof the cover, and the lower end terminates near the bottom of thechamberA'. This overflow-tube prevents the water from rising in thespace at and running over the top of the cooler should the plug orstopperC be allowed toretna-in too long in the tube .9.

p The upperporrion of the milk-can is provided with a plate, H, fittedover a vertical opening formed in its side. The plate may be of glass orother transparent substance, whereby the line of division between thecream and the milk cans can be seen. The side of the milk-can is furtherprovided wlth a curved opening, a, formed in a vertical plane, andhaving itsex- 'tremities practically in transverse line with theextremities of the transparent plate. A circular recess, b, is formed onthe outer side of the milk-can, and within this recess is centrallypivoted a vertical disk, L. This disk has a knob, 6, for rotating it,and is further provided with a discharge-spout, 61, located near theperiphery of this disk. This spout and the curved opening a are bothformed at the same distance from the pivoted center of the disk, so thatas the latter is rotated its spout is always in line. with said curvedopening. By turning the disk its spout is correspondingly moved todifferent heights, and by adjusting the spout in horizontal line withtheline of division between the milk and cream, as shown through thetransparent plate, the cream can be drawn off from the milk.

When this improved cooler is used without the employment of ice the corkO is kept in the tube 8, and the water (which is forced onto the top ofthe supplemental cover bywind'mill, pump, or any other suitable means)allowed to flow on top of supplemental cover and fill the main cover upto the top of the overflow-tube. overflow-tube down to near the bottomof the chamber A, and passes from the cabinet by a waste-pipe situatedslightly below the level'of the top of the cans. By this means aconstantcirculation is kept up, which answers all'the necessarypurposes. 7

In the foregoing specification I have 'described and in the drawingshave shown several parts of a milk-cooler patented to me October 26,1880;-but I would have it understood that I do not limit the use of myim- The water then flows through this provement claimed herein to thepeculiar construction of the can and other parts shown and described butnot claimed, as I consider myself at liberty to use any otherconstruetion of parts that will answer the necessary purposes.

Having fully described my. invention, whatI claim as new, and desire tosecure by Letters Patent,'is-

1. In a milk-cooler, the combination, withi'a water-chamber andmilk-cans, of a'co'ver having a depending rim which extends into thewater'chamber, a ventilating-tube extending above the cover and belowthe top of the cans, and a tube which conducts the waste ice-water fromthe surface of the cover into the water-chamber. I

2. In a milk-cooler, the combination, with the Water-chamber andmilk-cans, of a cover having an inwardly-extending rim, and providedwith a pipe adapted to convey the waste icewater from the surface of thecover, a rubber plugor stopper adapted to fit said opening, aventilating-tube passing through saidcove'r to a point below the top ofthe cans, and an overflow-pipe extending nearly to the bottom of thechamber, substantially ass'et forth.

3. In a milk-cooler, the combination, with'a water-chamber and a coverprovided with ventilating and waste-water tubes, of asupple mental coverprovided with a central upright cylinder having an independent bottom onwhich the ice rests, and perforations for the when the parts are inposition,substantially as set forth.

I 4. In a milk-cooler, the combination, with the water-chamber, of therack removably secured to the bottom thereof, and provided with sidepieces adapted to prevent the cans from being placed too near the sidesand ends of the chamber, so as to interfere with the closing of the top,cross-bars, and cans having lugs adapted to engage said cross-bars,substantially as set forth.

5. The combination, with the water-chain ber, of a rack removablysecured therein, the said rack being composed of side and end pieces,depending hangers, standards, and

dle by which it can be passed through the supplemental cover and closethe Waste-pipe without removing either cover, substantially as setforth. v

In testimony that I claim the foregoing I have hereunto set my hand this20th day of 7 March, 1882.

DAVID N. OALKLNS.
